Let me give a bit of background info first. My baby is 1 month old tomorrow. When he was 5 days old, we had to admit him to the hospital due to jaundice and dehydration. I was nursing around the clock and thought he was getting milk. He lost something like 1 pound in 2 days. They gave him IV for 24 hours and briefly put him in phototherapy (the jaundice was above normal range, but nothing too bad). Anyway, he was very slow to gain weight these last 4 weeks. Starting when he was 5 days old, from time to time I pumped and my husband gave him a bottle. It didn't seem to make a difference with my nursing.
The pediatrician has wanted us to supplement with formula at night to help him gain weight, so every 3 hours at night I nurse him for 15 minutes, my husband gives him about 2 ounces of formula through bottle, and I pump after nursing. I've been noticing him getting frustrated sometimes after about 15-20 mins of nursing when my milk is probably coming in slower. Our home care nurse (who's a lactation specialist, but not certified or anything) said not to worry; that it's normal now that he's older and he's just losing focus. He's pretty hyper when it happens, and latches on kinda haphazardly, doesn't get milk out, unlatches, and cries. I also want to mention there are times when he chokes during my first let down.
I spoke with a LLL leader who's a IBLCE, and gave her my son's history since birth. She said he has a lot of signs of posterior tongue tie. Tomorrow I'm going to see a pediatric ENT doctor to find out for sure. But since he doesn't know about forceful let down and nipple confusion, I figured I'd ask opinions here.
I don't know if I should mention that at 2 weeks, he didn't have a dirty diaper for 6 days. The pediatrician (who's old and very old school, by the way) said I needed to nurse more. I don't know how that's even possible since I nurse on demand nearly every hour. But since then, he goes about every 2-3 days, which he says isn't a problem for BF babies.
Since supplementing with formula at night, he gained 6 oz in a week. The pediatrician is satisfied and I don't need to see him for a month. But I really don't want to supplement with formula if I don't need to, or at least less (we give about 4 oz at night now). I have trouble pumping during the day since he nurses so often.
I hope I've given all the info you need. So much has happened since he was born. If you need anymore info, just ask. thanks.
